Missouri summers are brutal, and the people who feel it worst are the ones who keep working through it. If extreme heat made you sick on the job — heat stroke, heat exhaustion, or severe dehydration — you may be owed Missouri workers' compensation benefits, the same as any other on-the-job injury. The free consultation is free, and there is no fee unless we win.
Every summer, injured workers across central Missouri end up in the hospital with heat-related illness. Construction crews, roofers, landscapers, farm hands, and warehouse and factory employees face the highest risk. These injuries are real, sometimes fatal, and often covered.
Is heat-related illness covered by Missouri workers' comp?
Yes — when it arises out of and in the course of your employment. Heat stroke, heat exhaustion, and other heat-related illnesses are treated like any occupational injury if your work conditions caused or contributed to them. Extreme heat, no shade, no air conditioning, and heavy exertion all matter.
The legal test is whether your job exposed you to a greater risk of heat than you would face in normal life. Working a roof at 98 degrees, or a warehouse with no ventilation, is not the same risk the general public faces. That is why documenting the temperature, your duties, and the conditions is so important.
Common heat-related illnesses on the job
Heat injuries fall on a spectrum, and they can escalate fast. The most serious are medical emergencies.
Heat Exhaustion
Heavy sweating, weakness, nausea, and dizziness from working in extreme heat. Left untreated, it can progress to heat stroke.
Heat Stroke
A life-threatening emergency when the body can no longer cool itself. It can cause organ damage, fatalities, and lasting injury. Call 911.
Severe Dehydration
Fluid loss that can lead to heat cramps, fainting, and even heat-induced kidney injury after a long shift in the sun.
High-Risk Industries
Construction, roofing, landscaping, agriculture, warehousing, and manufacturing see the most heat-related illnesses each summer.
What to do if heat made you sick at work
Get medical care first — heat stroke is an emergency. Then protect your claim: report the injury to your employer in writing, note the temperature and your duties, and identify any coworkers who saw what happened. From there you can file your workers' comp claim.
Deadline: Missouri law requires you to report a work injury to your employer within 30 days. With heat illness, report it as soon as you are able — missing that window gives the insurance company an easy reason to deny your claim.
Hurt by heat on the job? Talk to someone who knows the system.
Before private practice, Chris Miller was a government attorney at the Missouri Department of Labor and administered the Division of Workers' Compensation — the state agency where these disputes are decided. He knows how insurers fight heat claims because he ran the system. No fee unless we win.

Heat-related illness claims are denied more often than most. Insurers argue the illness was not really work-related, or they blame a pre-existing condition like heart disease or age. Some point to a worker's health rather than the job site. Each of these arguments can be challenged with strong medical evidence and proof of the heat exposure your work required.
